Opens or creates a USD stage using `StageRootLayerPath_ as root layer, creating the root layer if needed. All future conversions will fetch prims and get/set USD data to/from this stage. Note: You must remember to callCleanup()when done, or else this object will permanently hold a reference to the opened stage!
